TOBACCO-PIPE.

SPECIFICATION forming part of Letters Patent No. 615,027, dated November 29, 1898.

Application filed December 14, 1897- Serial No. 661,866. (No model.)

To all whom, it may concern:

Be it known that I, JOSEPH J AQUE, a citizen of the United States, residing at St. Louis, State of Missouri, have invented a new and useful Tobacco-Pipe, of which the following is a specification.

My invention relates to tobacco-pipes, and has for its object to provide a pipe-bowl of such a construction and materials as to form an absorbent for a portion of the nicotine and impurities without the risk of being injured by heat, as in the case of bowls constructed solely of corncob or wherein a corncob lin ing is fitted loosely in a bowl-shell and out of contact with the inner surface thereof.

A further object of the invention is to provide means for preventing such contraction of an absorbent lining as to render the device inoperative.

Further objects and advantages of this invention will appear in the following description, and the novel features thereof will be particularly pointed out in the appended claims.

In the drawings, Figure l is a side View of a pipe constructed in accordance with my invention. Fig. 2 is aseotional view of the same. Fig. 3 is a detail view of the stopper or plug detached. Fig. 4 is a detail view of the false bottom or strainer-disk detached.

Similar letters and numerals of reference indicate corresponding parts in all the figures of the drawings.

The pipe-bowl A embodying my invention consists of an open-ended tubular element or lining 1, of corncob, fitted within an exterior element consisting of a protecting shell or cover 2, of wood or equivalent material, said tubular interior element being snugly or tightly fitted in place and being preferably secured by cement. It is well known that while corncob pipe-bowls are preferable, by reason of their absorbent qualities, the .inconvenience of their use consists, primarily, in the risk of cracking by the action of the heat after a comparatively short use. The interior element or lining is open-ended, as is the exterior element or shell, and the lower end of the former is fitted with a compressible elastic plug 3, of cork or equivalent material, of which there is no shrinkage due to heat or moisture, whereby said plug is firmly retained in position during the use of-the pipe and prevents the material contraction of the lining. This plug is provided with a cap 4, which covers the lower end of the shell and constitutes the bottom thereof, said shell and cap being made in any suitable ornamental configuration. The plug is preferably let into and cemented to the cap, as shown in Fig. 2, and the cap, in addition to covering and concealing the plug, forms a convenient means whereby the same may be withdrawn from the lower end of the bowl to facilitate cleansing the interior thereof.

The lining is preferably tapered exteriorly and interiorly toward its lower end and is also reduced or tapered in thickness toward its lower end, as shown in Fig. 2, its lower end being arranged flush with the lower end of the shell, and in order to divide the combustion-chamber 5 from the nicotine and saliva receptacle 6 I employ a false bottom 7, consisting of a perforated or interstitial disk, preferably of sheet metal, which is fitted in the bore of the lining at an intermediate point with its periphery snugly in contact with the surface thereof. This disk may be introduced at the upper end of the lining and forced downwardly until the peripheral contact is sufficient to maintain it in place; but in practice I prefer to provide said disk with peripheral points or spurs S for engaging the material of the lining. The stem-socket 9 consists of alined openings formed in the lining and shell below the plane of the false bottom and above the upper surface of the plug. This disk by fitting snugly in the bore of the lining prevents contraction of the lining above the plane of the stem B, and the plug performs a similar function below the stem, whereby the efficient communication of the stem with the interior of the lining is preserved in opposition to the tendency of the lining to contract. a

As above indicated, an important advantage of the construction described resides in the fact that the shell incloses the tubular lining snugly, and thus prevents expansion and splitting or cracking thereof, while the effect of the corncob lining upon the smoke is the equivalent of that obtained in a pipe of which the bowl is constructed solely of corncob. The durability of a corncob pipebowl is vastly increased by providing it with a snugly-fitting sheath, while the other properties thereof remain the same as in the ordinary construction.

A further advantage of the construction described resides in the fact that the rem0vable plug, by which access may be gained to the saliva-receptacle, has an efficient frictional contact with the inner surface of the corncob lining and is thereby held from accidental displacement, while its removal may be readily accomplished manually. Furthermore, in practice I prefer to concave or hollow out the upper surface of the stopper or plug to form a cup for the reception of saliva, nicotine, and other precipitates.

The stem of the pipe is provided with a redueed extension fitting snugly in alined lateral openings formed in the shell and lining of the bowl, and hence in case of any contraction of the absorbent lining due to the drying out of the moisture thereof the draft of the pipe will not be affected; but the peculiar construction and relative arrangement of the parts disclosed herein are designed to prevent this contraction of the bowl, particularly at its lower portion or contiguous to the plane of the point of attachment of the stem. The means adopted for preventing this contraction consist, in the first place, of the interstitial or reticulated disk, which is snugly fitted in the bore of the bowl above the plane of said lateral openings and bears peripherally against the walls of the bowl, and, in the second place, in the expansible plug 3, which extends upwardly into the bore of the bowl and serves to prevent shrinkage, said plug being located below the plane of said lateral openings. This expansible plug is preferably fitted in a seat formed in the upper side of the cap 4 in alinement and corresponding in diameter with the bore of the bowl, whereby the plug breaks the joint between the cap and the contiguous lower end of the bowl and permanently maintains a tight joint, which prevents leakage.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of this invention.

Vhat I claim is 1. A pipe having a bowl provided with an openended absorbent lining, and a plug fitted in the lower end of the lining to prevent contraction thereof, and a pipe-stem fitting in an opening in the bowl, near the plane of the plug, and extending through the lining, substantially as specified.

2. A pipe having a bowl comprising an open-ended absorbent lining and a snuglyfitting open-ended inclosing shell, said lining and shell being provided with registering openings, an expansible plug fitting in the lower end of the lining, to prevent contraction thereof, a perforate disk snugly fitted in a transverse position in the bore of the lining with its periphery in contact with the surface thereof to prevent contraction of the lining at that point, said registering openings of the lining and shell being arranged between the planes of the shell and disk, and astem fitted in said registering openings, substantially as specified.

3. A pipe having a bowl comprising an open-ended absorbent lining and a snuglyfitting open-ended inclosing shell terminating at its lower end flush with the lining, a cap covering the lower ends of the lining and shell and provided with a central depression, an expansible plug secured in said depression of the cap and fitted upwardly into the lower end of the lining, to prevent contraction of the latter, said lining and shell being provided with registering openings, and a stem fitted in said registering openings, substantially as specified.

l. A pipe having a bowl comprising an open-ended absorbent lining tapered downwardly in bore, and a snugly-fitting openended inclosing shell, said lining and shell being provided with registering openings, a stem,'of which the extremity is fitted in said openings, an expansible plug fitted in the lower end of the lining below the plane of said registering openings, to prevent contraction of the lining, and a perforated disk fitted in the bore of the lining above the plane of said registering openings, with its periphcry in contact with the surface of the lining to prevent contraction thereof, and provided with radial spurs engaged with the material of the lining, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

JOSEPH JAQUE.
